[Problems to be solved by the invention]
However, in the conventional connector, when each mounting portion is fastened to a board or the like with a screw, a tensile stress is generated in the connector body due to the fastening force of the screw, and this stress remains and causes distortion and deformation of the connector body. There was a point.
[0006]
The present invention has been made in view of the above-mentioned problems, and the object of the present invention is to reliably prevent distortion and deformation of the connector main body even if a tensile force is generated in the connector main body when fixing the mounting portion. It is to provide a card connector that can be used.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a connector main body having a card insertion slot on one end side, a plurality of card connection terminals provided on the other end side of the connector main body, and both sides of the connector main body in the width direction. In the card connector in which the connector body is attached to the attachment object by fixing each attachment part to an arbitrary attachment object, a length extending in the front-rear direction on the side surface of the connector body. A hole is provided, and a portion between the elongated hole and the attachment portion is formed so as to be elastically deformable in the width direction of the connector body, and the attachment portion is provided on the distal end side of the extension portion extending in the front-rear direction from a predetermined position on the lower side of the connector body. The base end side of the extending portion is formed so as to be elastically deformable in the vertical direction .
[0008]
As a result, when a tensile force is applied to the connector main body by fixing the attachment portion, the portion between the elongated hole and the attachment portion is elastically deformed in the width direction of the connector main body, and the proximal end side of the extension portion is elastically deformed in the vertical direction. The tensile force is absorbed. In this case, it is possible to form the vicinity of the attachment portion so as to be elastically deformable in the width direction and the vertical direction of the connector main body by simply providing the elongated hole and providing the extension portion in the connector main body.

It moves to the groove 32c and the lock of the slide member 31 is released. When the pressing of the card 1 is released, the engaging member 34 moves to the one end side of the locking member 32 along the third groove 32c as shown in FIG. 5, and the slide member 31 and the card 1 are connected to the connector main body by the spring 31c. 10 toward one end side.
[0020]
When the connector is attached to the board A, the screws 13 are inserted into the holes 11b of the attachment parts 11a of the connector body 10 and the screws 13 are fastened to the board A, so that each attachment part 11a is attached to the board A. Fixed to A. At that time, a tensile force in the width direction is applied to the upper housing 11 of the connector main body 10 by the fastening force of each screw 13, but as shown by the one-dot chain line in FIG. Since the flexible portion 14 that can be elastically deformed is formed in the width direction of the housing 11, the tensile force is absorbed by the elastic deformation of the flexible portion 14.
[0021]
As described above , according to the card connector, in the vicinity of the attachment portion 11a of the connector body 10, the flexible portion 14 that can be elastically deformed in a direction in which stress is applied to the upper housing 11 of the connector body 10 by fixing the attachment portion 11a. Since the tensile force due to the fixing of the attachment portion 11a is absorbed by the elastic deformation of the flexible portion 14, the upper housing 11 of the connector body 10 is not subjected to tensile stress, and the upper housing 11 Distortion and deformation can be reliably prevented.
[0022]
In this case, the long hole 11c extending in the front-rear direction is provided at the upper end of the side surface of the upper housing 11, and the portion between the long hole 11c and the attachment portion 11a is formed as a flexible portion 14 so as to be elastically deformable.

8 and 9 show another premise technique of the present invention. FIG. 8 is a perspective view of a main part of a card connector, and FIG. 9 is a plan view of the main part. In addition, the same code | symbol is attached | subjected and shown to the component equivalent to the said premise technique .
[0025]
In this card connector , the mounting portion 11a of the connector main body 10 is provided on the distal end side of the extending portion 11d extending forward from a predetermined position in the front-rear direction of the lower end of the side surface of the upper housing 11, and the proximal end side of the extending portion 11d is in the vertical direction. A flexible portion 15 that is elastically deformable is formed.
[0026]
That is, when a tensile force in the width direction is applied to the upper housing 11 by fastening each screw 13, the flexible portion 15 is elastically deformed upward as shown by a one-dot chain line in FIG. 9, and the tensile force is applied by the flexible portion 15. Absorbed.
[0027]
Therefore, in the connector the card, since the tensile force by fixing the attachment portion 11a can be absorbed by the elastic deformation of the flexible portion 15, without causing tensile stress in the upper housing 11 of the connector body 10, the upper The distortion and deformation of the housing 11 can be reliably prevented.
[0028]
In this case, the mounting portion 11a is provided on the distal end side of the extending portion 11d extending forward from the lower end of the side surface of the upper housing 11, and the base end side of the extending portion 11d is formed as a flexible portion 15 so as to be elastically deformable in the vertical direction. Therefore, the flexible portion 15 can be formed by a simple configuration in which the upper housing 11 is simply provided with the extending portion 11d, which is extremely advantageous in manufacturing.
[0029]
Figure 10 shows an embodiment of the present invention, provided with a long hole 11c to the upper housing 11, it provided the attachment portion 11a from the side lower end of the upper housing 11 on the distal end side of the extending portion 11d extending forward Is. As a result, the tensile force due to the fixing of the attachment portion 11a can be absorbed by the flexible portions 14 and 15 in the width direction and the vertical direction of the upper housing 11, respectively, so that the generation of tensile stress in the upper housing 11 can be more reliably performed. Can be prevented.
[0030]
11 shows another embodiment of the present invention, provided with a long hole 11c to the upper housing 11, mounting portion 11a provided from the side surface lower end of the upper housing 11 on the distal end side of the extending portion 11d extending rearward It is a thing. Thereby, like the said embodiment, the tensile force by fixation of the attaching part 11a can be absorbed by the flexible parts 14 and 15 to the width direction and the up-down direction of the upper housing 11, respectively.
[0031]
In each of the above embodiments, the card ejection mechanism 30 is shown. However, the present invention does not have a card ejection mechanism, and is directly inserted into and removed from the terminal in the connector body while holding the card. It can also be applied to.
[0032]
【The invention's effect】
As described above, according to the card connector of the present invention , it is possible to absorb the tensile force to the connector main body generated when the mounting portion is fixed, so that no tensile stress is generated in the connector main body. Distortion and deformation can be reliably prevented. In this case, the vicinity of the attachment portion can be formed to be elastically deformable with a simple configuration, which is extremely advantageous in manufacturing.
